I have my mag at 1500 right now and all my duncans are doing great. Maybe it is something else? The only time I have seen a duncan died was in a tank with a lot of nitrates. I actually thought they were nearly undestructible before as they are very resistant.

One of mine is nearly 3 year old and has grown too many heads too many times.

They do need lights and they do need food. Mine really swell large when the MH is on.

Once I had one did the brown jelly and cought it in time. I took it out of the water and put peroxyde right on the affected area and it healed in 2 days.

What is your alk at?
